I was at a similar decision-making point as you a couple of years ago. I had a single property rental in Silicon Valley and one in the Tri-Valley that were cash-flowing, but not by much. I sold one and did a 1031 into a 4-plex in Modesto. I felt I had already benefited from the appreciation and now it was time to benefit from more cash-flow. It worked out and I was happy with the decision. So I did it again and did another 1031 from 1 rental into 2 duplexs' in Modesto. Same result. They're not appreciating as much which is to be expected, but the cash-flow is significantly more. No regrets. I'd do it all over again. In fact... I might do it again with the last Bay Area rental we have, but not in a hurry. I had also considered investing out of state in Saint Louis, which I may still do. I haven't written off that idea yet, but for now my comfort zone is 1 hour from the Bay Area, although it's extremely rare that I ever personally visit one of my properties.
